7d165f6451 mfd: qcom-spmi-pmic: Document ten more PMICs in the binding 
Update the binding with eight more SPMI PMIC compatibles found in the
PMIC info list in the Qualcomm socinfo driver and add the two PM660
related PMICs supported by the SPMI PMIC driver but are missing from the
document.

Then remove the duplicate entry for pma8084.

6ae210f1b5 mfd: janz-cmoio: Replace snprintf in show functions with sysfs_emit 
show() must not use snprintf() when formatting the value to be
returned to user space.

Fix the following coccicheck warning:
drivers/mfd/janz-cmodio.c:157: WARNING: use scnprintf or sprintf.

Use sysfs_emit instead of scnprintf or sprintf makes more sense.

fae2570d62 mfd: altera-sysmgr: Fix a mistake caused by resource_size conversion 
The resource_size defines that:
	res->end - res->start + 1;
The origin original code is:
	sysmgr_config.max_register = res->end - res->start - 3;

So, the correct fix is that:
	sysmgr_config.max_register = resource_size(res) - 4;

The Arizona driver has both some devices which only have an I2C
interface and some which only have a SPI interface. Currently both of
these share an of_match table, but this means inapproriate compatibles
are available for each interface. Tidy this up by creating a table for
each interface listing only the appropriate compatibles.

d3546ccdce mfd: qcom-pm8xxx: switch away from using chained IRQ handlers 
PM8xxx PMIC family uses GPIO as parent IRQ. Using it together with the
irq_set_chained_handler_and_data() results in warnings from the GPIOLIB
(see 461c1a7d47 ("gpiolib: override irq_enable/disable"))
as in this path the IRQ resources are not allocated (and thus the
corresponding GPIO is not marked as used for the IRQ. Use request_irq so
that the IRQ resources are proprely setup.

8163fbd971 mfd: max14577: Do not enforce (incorrect) interrupt trigger type 
Interrupt line can be configured on different hardware in different way,
even inverted.  Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.

The Maxim 14577/77836 datasheets describe the interrupt line as active
low with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.

The interrupt line is shared between PMIC and charger driver, so using
level sensitive interrupt is here especially important to avoid races.
With an edge configuration in case if first PMIC signals interrupt
followed shortly after by the RTC, the interrupt might not be yet
cleared/acked thus the second one would not be noticed.
